IDs and Classes

If you would prefer to only change one specific instance of a HTML element, you would give it an ID.

<p id="redbox">This is the only red box.</p>

To refer to this element, you would use a pound sign ( # ) followed by the id name in the CSS code.

#redbox {  }

If you would prefer to change more than one HTML element, you would give it a class.

<p class="bluebox">This is the first blue box.</p>
<p id="redbox">This is the only red box.</p>
<p class="bluebox">This is the second blue box.</p>

You can also give different HTML elements the same class.

<div class="bluebox">This div is blue.</div>
<p class="bluebox">This paragraph is also blue.</p>

To refer to these elements, you would use a period (.) followed by the class name in the CSS code.

.bluebox {  }

Close Tag

Add this line to tell the computer you are finishing specifying CSS.

</style>

Simplify

Once you've put together several codes, you may find your page looks a little messy. For example, if your codes look like this:

<style type="text/css">
a:link { font-weight: bold; color: #FF0000; }
</style>
<style type="text/css">
a:visited { color: #0000FF; }
</style>
<style type="text/css">
a:active { color: #00FF00; }
</style>

It is very easy to get rid of four lines. Get rid of all the <style> tags except for one at the beginning and one at the end. Allow me to demonstrate:

<style type="text/css">
a:link { font-weight: bold; color: #FF0000; }
a:visited { color: #0000FF; }
a:active { color: #00FF00; }
</style>

If you have more than one element with the same specifications, like this:

<style type="text/css">
form { background-color: #FFFF00; }
hr { background-color: #FFFF00; }
</style>

You can put the names of the elements together, but they must be separated by a comma, like this:

<style type="text/css">
form, hr { background-color: #FFFF00; }
</style>

If you have colours specified in your CSS that follow the patter #AABBCC, where the first two letters are the same, the second two are the same, and the last two are the same, you can shorten it to #ABC. The above code would change to this:

<style type="text/css">
form, hr { background-color: #FF0; }
</style>
